While true, the distractedness (on the part of the pedestrian or the driver) doesn't absolve the driver of their responsibility to yield in this scenario. A driver who hits a pedestrian in this scenario will be subject to criminal and

I do the same, but I do worry about the security aspect. I don’t like the idea of having a bunch of devices on my network. I put the IoT things on a guest network, but I still feel iffy about it. I’m sure there are better solutions, but all

When I was doing Qt development, getting CMake to build Qt projects properly was absurdly difficult. CMake had added some half-baked first class functions for building Qt (it's insane that a build system has first class knowledge of ce

I misunderstood your question. I don't know of the specific reasons; presumably they're the same reasons that intermediate C programmers can't reliably write secure C.

I think that’s what I meant as well, but I’m not sure what you mean by “service orchestration”. If Kubernetes is an example of a service orchestrator, then I think something like EC2 would be the unikernel analog.
130.
by weberc2 7y ago
“Container” and “OS” don’t mean anything in the context of unikernels. Unikernels are applications with everything they need to run (on bare metal or a hypervisor) baked into the application. So there is no OS to speak of, and the “orchestr

Fair point. Perhaps my issue was less about the visibility of the annotation and more that the types in functional languages tend to be more abstract or complex (e.g., monads, functors, etc) and harder (for me) to reason about despite the c

I actually find that excessive type inference is much harder to understand. It’s almost like the worst of dynamic and static types. You have no idea what the types are, but you know it won’t compile because of a cryptic error message.

I don’t think I’m the one missing the point. You seem to be rebutting points I didn’t make, like other languages (or magic bullets) afford a bug count of zero. You also seem to be ignoring my point, which is that C is in a different ballpar

Virtually no one can write secure C code. This is different than “other languages allow some people to write insecure code occasionally”.
137.
by weberc2 7y ago
Many of the most expert C programmers have reported an inability to write secure C code. But you’re right that my understanding of the language is incorrect; that’s largely my point. There are so many oddities and exceptions and surprises t

It’s roughly JSON = Union[Dict[str, JSON], List[JSON], str, bool, int, NoneType] TypedDict isn’t for arbitrary JSON, but it is really cool.

by weberc2 7y ago
Ah, I see. Yes, that’s true. You would need to return a bool alongside it or similar, but the best practice is to use an interface for sure.

Linting for WithStack seems like it might be tough since you want to make sure the error was annotated exactly once (I think that’s the intended use, anyway?). The linter would need to know whether or not a fallible function call has annota

I’m not talking about being clever, I’m talking about writing code that meets some baseline standard for security, correctness, and cross platform functionality. The issue with C is that standard, “unsurprising” code often behaves unexpecte

Also the circular imports was the least of the problems I’ve run into with mypy. They still can’t model a JSON type because it is recursive.

As far as I know, name mangling only exists because linkers don’t have a notion of namespaces. If you fix linkers, then there is no need to mangle.

I love writing C when I haven’t written C in several years. It feels nostalgic and simple and elegant in my mind, and then I remember all of the issues I run into and how none of them have good, clear solutions. Things like writing cross pl

You can abstract over a struct as easily as a pointer, and structs work fine for satisfying interfaces. Specifically, structs make it a little harder for someone to inadvertently mutate things (passed by copy) and because they can’t be nil

I don’t know man. I have scarcely seen bugs like these and most of them seem pretty conspicuous to me (maybe I’ve just been writing Go long enough), but I see loooads of uncaught Python (and Java) exceptions internally and from high-profile

It doesn’t require it. Instead it could just generate the same error handling boilerplate. But I think it would be a mistake versus general purpose (generic) sum types a la Rust.
149.
by weberc2 7y ago
I don’t buy the “huge pain” argument. I write lots of Python and Go, and the error boilerplate is a non-issue. I also appreciate that it’s explicit instead of implicit.

It appears to be specific to Java. Other languages don’t seem to exhibit high memory usage with the same frequency or severity as Java, and that’s not because developers of other languages spend more time optimizing. If indeed this observed
